OIL CUP. Y

Application filed August 20, .1923. Serial No. 658,286. 7

This invention is a novel improvement in oil cups, and its object is to produce a simple eflicient oil cup which will be neat and attractive in appearance and will have a closed oil chamber with a single inlet and a single outlet actuated closing device for the inlet; and a wick discharge through the outlet.

lVe will explain. the invention with reference to the accompanying drawings, which illustrate a complete cup embodying the invention; and summarized in the claim the essential features of the cup and novel constructions of parts for which protection is desired.

In said drawings:

Fig. 1 isa side View of the complete cup.

Fig. 2 is a vertical sectional View through the cup.

Fig. 3 is a sectional view of the cup on the line 83 Fig. 2.

F ig. l is an enlarged detail of the filling hole and closure section on the line l4t, Fig. 3.

As shown the cup comprises a base portion or body 1, and a cover or top portion 2.

The body 1 is formed preferably of drawn metal, and has an enlarged cylindrical portion 1- at its upper end and a reduced portion 1 below portion 1 but connected therewith by an inverted conical portion 1*; and below the part 1 the body is further reduced in diameter as shown at 1 and the lower end of the part l is closed as shown, except for a small aperture 1 for the outlet of the oil, or wick 4 by which the oil is fed from the cup. The part 1 is preferably externally screw threaded as shown to engage threaded opening in the body to which the cup is to be attached. The part 1 is preferably externally multifaceted, being indicated as hexagonal, thereby imparting a neat attractive appearance to the cup.

The cover 2 is preferably made from drawn metal, and preferably cylindrical, being slightly larger in diameter than part 1 of the body 1 and can be readily drawn in cup shape. The cover 2 has its upper end 2" closed, and as originally drawn the lower portion 2 of the shaped body is internally slightly tapered downwardly and outwardly; and the part 1 of the body is externally slightly tapered upwardly and inwardly, so that the parts 1 and 2 telescope, as indicated in Fig. 2, the tapered portions being of such diameters thatthe part 1 can be forced into the part 2 and the opposed tapered portions will make a tight wedgingfit therebetween asshown in Fig. 2. When first so assembled the lower edge of the body 2 depends slightly below the part 1, as indicated in dotted lines 2 in Fig. 2, and after the body and cover are fitted together, as described the part 2 is turned in and flanged under the part 1 and against the tapered part 1 of the body, as shown, thus inseparably uniting the body and cover which together form an oil tight cup.

Both the body and the cover 2 can be read ily drawn. from sheet metal, and when united as described forms-a cup which is oil tight except for the outlet opening 1 in the body, and a feed opening 2 in the top 2 of.

the cover, which opening is closed as hereinafter referred to.

In the top 2, preferably near one side thereof, is an aperture 2 forming an inlet or feed opening which is normally closed by a suitable stopple. Preferably the stopple 3 is formed on or attached to the free end of a spring 3 inside of the cover. Preferably the spring 3 is a flat spring and stopple 3 is formed integral with one end of the spring 3, by suitably stamping the same, and the stoppleis of such size that it will normally completely fill the opening 2*, and the outer end of the stopple is flush with the outer surface of the cover, so as to leave no depression or place wherein dirt or sediment will collect in or around the filling opening 2.

The stopple 3 is preferably near one end of spring 3 and the other end of this spring is fixedly attached to the inside of the top 2 and within the cover. Preferably the spring 3 is riveted to the top, as indicated in the drawing. The rivet is preferably formed by pressing an elongated lug 2 in the top 2 of the cover; and the spring 3 has a corresponding elongated hole punched in it to fit over this elongated lug, and then the head of the lug is swagcd as indicated in the drawings to securely retain the spring in place. As the spring cannot swing the stopple 8 cannot get out of alinement with the hole 2. The spring is preferably bowed as at 3 between the rivet and the stopple so that the stopple may be pushed inwardly by external pressure; as by' pressing the spout of an oil can thereagainst, while filling the cup with oil;'and when the pressure on the stopple is removed the opening 2 is closed from the inside by the stopple under the action of the spring 3. Spring 3 is preferably wider and longer than the stopple and the aperture 2* so that oil or grease will be effectively prevented from escaping from the cup through the inlet aperture. The oil or grease passes from the cup through the outlet aperture 1 to prevent too rapid flow of grease or oil, a wick 4 which may be of any suitable capillary material is passed through the aperture 1 and such Wick is enlarged as at 4 within the cup to prevent its being pulled therefrom. It will be seen that the body and cover of the cup are oil tightly connected by the tapered joint between the parts 1 2 and the inturned portion 2; that the only openings in the cup are the inlet or filling opening 2 and the outlet opening P; that the filling opening is automatically closed by the spring supported stopple 3, which spring is held in place by the elongated rivet in suchmanner that the stopple cannot move out of alignment with the filling opening; that the stopple is so formed that its outer end is flush with the outer end of the cover when the stopple is closed; that there are no points or depressions or holes for collection of dirt; that the enlargement in the oil discharge wick prevents the same from being pulled out of the cup the length of the wick Within the cup is sufficient to insure that all oil will be drained from the cup; and that the cup has a smooth exterior surface and attractive ap pearance.

lVhat we claim is The herein described oil cup comprising a a hollow body and a hollowcomplemental cover, the lower portion of the cover being internally slightly tapereddownwardly and outwardly and the telescoping upper portion of the body being externally slightly tapered upwardly and inwardly, the tapered portions being of such relative diameter that the telescoping thereof will make-an oil tight wedging fit therebetween; the lower end of the cover being closely int-urned against the body to fixedly and inseparately unite the body and cover.

In testimony that We claim the foregoing as our own, we affix our signatures.
